## Lessons Learned

- Confidential data types (passwords, credit card info) were successfully protected, indicating strong segmentation or specific security controls around financial systems.
## Recommendations
- Implement or enhance continuous monitoring solutions specifically focused on tracking intellectual property or customer data discussions/listings on dark web forums and adversarial communication channels.
- Review and audit access controls to critical customer databases to ensure the "principle of least privilege" is strictly enforced.
- Mandate employees to be vigilant against phishing attempts, as initial access vectors often involve social engineering directed towards staff.
